So I went on a little offroad adventure and got a rock stuck between my backing plate/dustgaurd/whatever its called and my front left brake rotor. I got out the jack, took the wheel off and removed the rock (while not being directly under anything like I NEVER do). I usually always pull the E brake but recently it has become stretched and in need of adjustment so I didn't bother (stupid). the driveway is on a very slight incline and I didn't block the wheels so you knoooow what happened..
